FLOOR-DRAIN.

I Specification of Letters Patent. Patented Sept. 28, 1909- Appkicationfiled November 11, 1907. Serial No. 401,584.

To all whom it may concern:

Be it known that I, GEORGE J. DEHN, a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Floor- Drains, of which the following is a full,

' has been laid, and which when connected to thedrain-pipe cannot bedisplaced while the floor is being laid.

The invention further. designs to provide a combined drain and trap ofimproved construction in which a body of water supplemental to that inthe trap-pipe, is retained to prevent seal in the trap-pipe frombecoming iiie-J ective froifh evaporation of the liquid therein.

The invention still further 'designs to provide a drain and trap ofimproved and simpie construction, the several members whereof can bequickly and easily connected against displacement and which can beproduced at a low cost.

The invention consists in the, several novel features hereinafter setforth and more particularly defined by claim at the conclusion hereof.

In the drawings: Figure 1 is a vertical section of a device embodyingthe invention. Fig. 2 is a plan. Fig. 3 is a horizontal section on line33 of Fig. 1, the drain-pipe and basin being shown in relative positionassumed before the latter has been turned to secure or look it to saidpipe.

A trap-pipe A is formed with the usual bend a disposed below the lowestportion of the orifice in the return-bend or horizontal portion a ofsaid pipe to form a chamber for a body of water which forms a seal topreventobjectionable gases from the pipe or sewer to which it may beconnected, from escaping through the inlet-terminal of the trap-pipe.The outlet-terminal of the trappipe is provided with a flange a wherebyit may be secured to a section of pipe leading to the sewer ordischarge.

The inlet terminal a of the trap extends vertically and'is provided withan integral annulus or flange a adapted to form a seat or wall for thebase-rim b of a drain-receiver B. The outer wall I) of the receiver isflared upwardly or extends outwardly and upwardly from its base-rim toform a receiving-basin and is provided with a top-flange or rim b Anannular recess or shoulder 79 is formed in the receiver to retain aperforated: strainer-cover C which usually is disposed so it will beflush with the top of the basin and removably held therein, to provideaccess, when desired, to the trap and basin.

A lock or connection is provided between the trap-pipe and the receiverwhereby the basin will be secured against displacement with the pipe anda water-tight joint is provided between the pipe and the basin. Thisconnection comprises a series of ribs or lugs a, integrally formed onthe trap-pipe, and a corresponding series of notches b in the base ofthe receiver. The lower ends of said lugs are disposed so the inner edgeof said Tim will pass between said lugs andthe flange a and adjacenteachof the notches If is an inclined or wedge-surface Z) which isadapted to be driven beneath the lower ends of lugs u. and constitute a\\cdge-connection whereby the recciver-basin is securely held so itsbase will be tightly hold against the pipe-flange a." to form a tightconnection thcrebetween. Usually a coating of suitable material, such aswhite-lead is placed on the top of the flange or the bottom of the basinto make the connection water-tight. T 0 connect the basin to thedrain-pipe A it is only necessary to slip the receiver over the upperend of the pipe, with the notches If in rogistry with the ribs (1 Whenthe basin rests on the flange a", a slight turn of the basin will causethe wedge-surfaces I) to pass beneath said ribs and then the basin willbe securely connected to the drain-pipe and against displacement.

It is customary, in practice, to install the drain-pipe and receiverbefore the floor or quickly installed and which avoids all likeli- Ihood of being displaced or disconnected when the floor, usually ofconcrete and cement is being laid.

The inlet-terminal o extends above the base of receiver-basin B andrcsultantly an has on theouter side of said pipe-terminal of, and in,the device, and prevent undue evaporation of the water in the trap inthe drain-pipe.

The invention has several important ad-' vantages. It provides a drainand trap which may be quickly and easily connected and secured togetherso displacement is avoided. It provides. a device which is exceedinglysimple in construction and eiiicient in operation, and one in which asupplefinental body of Water is provided to prevents evaporation of thatin the trap.'

The invention is not to be understood 'as restricted to the precisedetails shown and described since these may be modified within the scopeof the claims, without departing from the spirit and scope of theinvention. 1

Having thus described the invention, what I' claim as new and desire tosecure by Let ters Patent, is:

1. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein and an upwardly extending inlet-terminal, a re ceiver-basinhaving a strainer-top, a slip and interlocking wedge connection betweenthe basin and the upwardly extending terminal of said'pipe for securingthe basin around the pipe so that a water-tight joint will be formedbetween the pipe and the basin.

2. in a floor-drain, the combination of a. drain-pipe having a trap-bendtherein and an upwardly extending inlet-terminal, a re ceiver-basinhaving a strainer top and a slip and interlocking wedge connectionbetween the basin and the upwardly extending terminal of said pipe, theinterlocking parts of said. pipe being on the outer side thereof and inthe basin.

3. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein, an upwardly extending inlet'terminal, a receiver-basin having astrainer-top, an annulus on the outer side of said pipe, terminal, and aslip and interlocking connection between the basin and the upwardlyextending terminal of said pipe for securing the basin so a watertightjoint will be formed between theannulus and the basin.

l. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein, an upwardlyextending inlet-terminal, a receiver-basin having astrainer top, an annuand interlocking connection between the .basinandthe upwardly extending terminal of said pipe, for seciiring the basin soa water-tight joint will be formed between the annulus and the basin.

. 5. In a floor-drain, the combination of a drain-pipe having atrap-bend therein and an upwardly extending inlet-terminal, a receiver-basin having a strainer-top, an integral flange onsaidpipe-terminal, and a slip and interlocking connection between thebasin andithe upwardly extending terminal of said pipe, for securing thebase of said basin against said flange to form a water-tight connection.

6. In a floor-drain, the combination of a drain-pipe having. a trap-bendtherein and an upwardly extending inlet-terminal, a re ceiver basinhaving a strainer top and an :opening in its bottom through which saidterminal extends, and a slip and interlocking wedge connection betweenthe basin and the upwardly extending terminal of said pipe to form aWatertight joint between the bottom of the basin and the pipe terminal.

7. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein-and an upwardly extending inlet-terminal, a receiver-basinhaving a strainer top and an opening in its base through which saidterminal eirtends, an annulus on'lhe outer side of saidpipe-terminal','and a slip and interlocking connection between the basinand the upwardly extending terminal of said pipe for holding the basinagainst said flange to "form a watentiglit connection.

8. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein and an upwardly extending inlet terminal, a re ceiver-basinbuying a strainer-top and an opening through it base through which saidterminal extends, interlocking parts on the outer side of'f saidiplperminal, and the base of said basin respectively. and a flange below theupper end of said terminal and on the outer side thereof and againstwhich the base of the basin will be held by said interlocking parts.

'9. In a floor-drain, the combination of a drain-pipe having a trap-bendtherein and an upwardly extending inlet terminal, a drain-receiverhaving a strainer-top and a base having an opening therein through whichsaid terminal extends, outwardly pro jecting lugs on the outer side ofsaid pipeterminal, and an annulus on said pipe-ten minal and below theupper end thereof and beneath said lugs, the base of said basin be 'ingprovided with notches adapted to-resspm an upwardly extendinginlet-tez'minsl, a receiver-basin having a strainer-top and. an openingthrough which said terminal extends, the bas of said receiver beingbelow the upper and. of said pipe to provide a watebchznnber around H16upper par'tion of said terminal, and a slip and iilteflosking GEORG -1J.
